U.S. stocks declined Tuesday as rising oil prices and a surge in Treasury yields pressured technology shares, with semiconductor companies leading losses amid renewed Middle East uncertainty and concerns over inflation and borrowing costs.

Wall Street finished lower Tuesday as investors moved away from high-growth technology stocks after renewed Middle East tensions pushed oil prices and Treasury yields higher.
Semiconductor shares absorbed some of the heaviest selling, reversing part of a recent rally fueled by strong investor enthusiasm surrounding artificial intelligence.
The market pressure intensified as fading expectations for a Middle East peace agreement drove crude prices upward. Higher energy costs contributed to renewed inflation concerns and a sharp move in government bond yields.
The yield on the 30-year U.S. Treasury climbed to its highest level since 2007, while the 10-year Treasury yield reached its highest point since January 2025.
Those moves weighed particularly heavily on technology companies, whose valuations can be more sensitive to changes in interest rates because investors often place significant value on profits expected years into the future.
“It starts off almost like a domino effect. Talks break down. That leads to oil prices going up. That leads to higher inflation expectations and bond yields rise,” said Burns McKinney, portfolio manager at NFJ Investment Group.
He added that “every time bond yields rise, that tends to disproportionately hit the technology names.”
According to preliminary closing data, the S&P 500 dropped 51.97 points, or 0.67%, to 7,692.10.
The Nasdaq Composite fell 350.45 points, or 1.31%, to 26,294.46, while the Dow Jones Industrial Average declined 115.93 points, or 0.22%, to 53,343.85.
Technology was the biggest drag among the S&P 500’s 11 major sectors, both in terms of index points and percentage losses.
Chipmakers were among the most influential individual decliners.
Nvidia, the leading artificial intelligence chipmaker, fell alongside memory-chip producer Micron Technology.
Micron’s decline came after its shares had gained nearly 18% over the previous five trading sessions.
Data-storage companies Sandisk and Western Digital also suffered significant losses, while the Roundhill Memory ETF dropped after posting gains for five consecutive sessions.
The selloff interrupted momentum in a group of stocks that had benefited from heavy investor demand tied to AI spending and memory-chip growth.
“There’s nothing that can crack a momentum rally quite like interest rates moving higher and you’re getting evidence of that today,” said Tony Welch, chief investment officer at SignatureFD.
Welch said the rise in yields also indicated that Federal Reserve policy may be too accommodative relative to the current outlook for economic growth and inflation.
As investors reduced exposure to technology and other high-growth stocks, money moved toward more defensive portions of the market.
Healthcare and consumer staples attracted increased demand during the session.
Energy shares also outperformed much of the broader market as crude prices remained higher.
Wall Street’s closely watched fear gauge rose to its highest level since Aug. 5, reflecting increased investor unease.
Oil futures had climbed more sharply earlier in the day before giving back much of those gains during afternoon trading.
U.S. crude ultimately settled 0.5% higher after Iran threatened to adopt a “fully offensive” military posture and Washington ruled out extending a ceasefire agreement.
Those developments contributed to concerns that a prolonged conflict could keep upward pressure on global energy prices and, in turn, inflation.
The increase in bond yields became a central concern for equity investors because higher borrowing costs can weigh on corporate investment and reduce the relative appeal of stocks compared with fixed-income assets.
The effect was especially noticeable in technology, where companies whose valuations depend heavily on future earnings were hit hardest.
Elsewhere in the market, Home Depot shares edged higher after the home-improvement retailer reported second-quarter sales that exceeded estimates.
Investors are now turning their attention to additional retail earnings later in the week, including results from Walmart.
Markets are also awaiting the release Wednesday of minutes from the Federal Reserve’s July meeting, which could provide additional insight into how policymakers are evaluating inflation, economic growth and the path of interest rates.
Another major test for the market’s artificial intelligence trade will come with Nvidia’s next quarterly earnings report.
The chipmaker has been a major force behind the technology sector’s recent gains, making its upcoming results an important indicator of whether enthusiasm surrounding AI-related growth can continue despite the renewed pressure from higher interest rates.
Tuesday’s trading showed how quickly geopolitical developments can move through financial markets, with concerns over the Middle East first lifting oil, then raising inflation expectations and Treasury yields before ultimately putting pressure on some of Wall Street’s strongest-performing technology stocks.
